Scientists Edit Human Embryo Genes With Startling Precision

Scientists Edit Human Embryo Genes With Startling Precision: Researchers relied on a newer gene-editing technique that may make it possible to engineer embryos, a prospect that has long alarmed bioethicists. By Carl Zimmer Scientists at Columbia University have edited the DNA of early human embryos with unprecedented accuracy, an achievement that could open the way to babies engineered with particular characteristics. The prospect
